Add MORSE_Desc_Create_OOC, which is like MORSE_Desc_Create, but does not
actually allocate a matrix, thus letting the runtime allocate on-demand the
tiles, possibly pushing them to the disk.

Add a --ooc option to tests to enable this.

    - use (starpu_cpu_func_t) 1 trick, same as cuda_func
    - cpu funtions are not defined anymore avoiding the dependency to coreblas
    - add #if !defined(CHAMELEON_SIMULATION) where it is needed
    - remove dependency to the coreblas library (become useless)
    - remove useless simucblas, simulapacke libraries
    - remove CHAMELEON_SIMULATION_MAGMA cmake variable and definition
      - keep using CHAMELEON_USE_CUDA and CHAMELEON_USE_MAGMA to consider CUDA kernels
      - this avoid to introduce useless new variables
    - work on messages

to change the default values for tag_width(=31) and tag_sep(=24).
Today, it serves only with starPU.

MPI tag upper bound: MPI_TAG_UB is included (so on most platform the default values tag_width=31, tag_sep=24 are ok)
